Seedling Diseases of Soybean

  • Several fungal pathogens can cause soybean seedling diseases, which can slow germination and plant growth, and even cause seedling death.
  • Cool temperatures and wet, poorly drained soils favor disease development.
  • Fungal pathogens can be difficult to manage once they are present within the environment, sopreventative measures provide the best control.
